Stage I represents the formation of the massive magnetite ore and the late stage magnetite ± apatite ± amphibole ± quartz ± chalcopyrite veins. Stage II
overlaps with stage I and includes the main copper ore forming event characterized by chalcopyrite and bornite. Stage III (post ore stage) involved the formation of lower temperature veins with quartz ± amphibole and some minor copper sulfides. The low temperature stage (IV) did not involve mineralization and is characterized by low temperature assemblages. It is known to a depth of about 400 m with an estimated tonnage of 52.6 Mt at 51.5% Fe. Magnetite is the dominant ore mineral with hematite only occurring as veins cutting the magnetite or as partly altered magnetite grains.
